## Contents
<a name="API_Container_Contents"></a>

 ** command **   <a name="Lightsail-Type-Container-command"></a>
The launch command for the container.  
Type: Array of strings  
Required: No

 ** environment **   <a name="Lightsail-Type-Container-environment"></a>
The environment variables of the container.  
Type: String to string map  
Required: No

 ** image **   <a name="Lightsail-Type-Container-image"></a>
The name of the image used for the container.  
Container images sourced from your Lightsail container service, that are registered and stored on your service, start with a colon (`:`). For example, if your container service name is `container-service-1`, the container image label is `mystaticsite`, and you want to use the third (`3`) version of the registered container image, then you should specify `:container-service-1.mystaticsite.3`. To use the latest version of a container image, specify `latest` instead of a version number (for example, `:container-service-1.mystaticsite.latest`). Lightsail will automatically use the highest numbered version of the registered container image.  
Container images sourced from a public registry like Docker Hub don't start with a colon. For example, `nginx:latest` or `nginx`.  
Type: String  
Required: No

 ** ports **   <a name="Lightsail-Type-Container-ports"></a>
The open firewall ports of the container.
